prev() does not filter by selector

[juandavid1707@…]

See this ​http://jsbin.com/ocuxad/4/edit.

Or,

in javascript

x=$('select#per_page').prev('#page');
console.log($('select#per_page'));
console.log(x); // returns []

in html

<input id="page" name="page" type="hidden" value="1">
 <input id="per_page" name="per_page" type="hidden" value="25">
 <select id="per_page" name="per_page">
  <option value="10">10</option>
  <option value="25">25</option>
  <option value="50">50</option>
 </select>

That markup is invalid, it has two elements with the same id. Please ask for help on the forum or on StackOverflow. Also see the documentation for .prev(), it seems you expect the method to look back until it finds what is in the selector and that is not the case.
